1,4-naphthoquinones (NQs) catalytically oxidize H2S to per- and polysufides and sulfoxides, reduce oxygen to superoxide and hydrogen peroxide, and can form NQ-SH adducts through Michael addition. Here, we measured oxygen consumption and used sulfur-specific fluorophores, liquid chromatography tandem mass spectrometry (LC-MS/MS), and UV-Vis spectrometry to examine H2S oxidation by NQs with various substituent groups. In general, the order of H2S oxidization was DCNQ ~ juglone > 1,4-NQ > plumbagin >DMNQ ~ 2-MNQ > menadione, although this order varied somewhat depending on the experimental conditions. DMNQ does not form adducts with GSH or cysteine (Cys), yet it readily oxidizes H2S to polysulfides and sulfoxides. …

Newborn mammalian cardiomyocytes quickly transition from a fetal to an adult phenotype that utilizes mitochondrial oxidative phosphorylation but loses mitotic capacity. We tested whether forced reversal of adult cardiomyocytes back to a fetal glycolytic phenotype would restore proliferative capacity. We deleted Uqcrfs1 (mitochondrial Rieske iron-sulfur protein, RISP) in hearts of adult mice. As RISP protein decreased, heart mitochondrial function declined, and glucose utilization increased. Simultaneously, the hearts underwent hyperplastic remodeling during which cardiomyocyte number doubled without cellular hypertrophy. Cellular energy supply was preserved, AMPK activation was absent, and mTOR activation was evident. In ischemic hearts with RISP deletion, new cardiomyocytes …

Improving Quality Of Life In Menopausal Women Through A Best Practice Protocol: The Use Of Hormone Therapy, Mindfulness-Based Module And Exercise, Claire Czerwonka

Evidence-Based Practice Project Reports

Menopause is a normal process of aging, but many of the symptoms negatively impact women’s day-to-day quality of life (QOL), as well as activities of daily living, physical and mental health (ACOG, 2014). Generally, systemic estrogen hormone therapy is indicated for menopause-related vasomotor symptoms, but there is no research further addressing QOL issues or lifestyle management in addition to hormone therapy. The purpose of this evidence-base practice (EBP) project was to implement a menopause protocol to address QOL issues in menopausal women with the use of hormone replacement therapy, education through an online mindfulness module, and the use of exercise. …

The Not-So-Benign Sickle Cell Trait: A Case Of Renal Medullary Carcinoma, Fatima Halilu, Siddartha Guru, Fuscaldo Joseph

Journal of Community Hospital Internal Medicine Perspectives

Sickle cell trait (SCT) has long been considered a benign carrier state with malarial protection, but carriers can be affected by increased venous thromboembolism, exercise-related injury, renal complications and very rarely a fatal renal malignancy. Renal medullary carcinoma is a very rare and aggressive renal tumor described almost exclusively in sickle cell trait. A review of the current literature provides clues to this link and describes trends expected in these cases. We report a case of renal medullary carcinoma in a 32-year-old female with known sickle trait who presented with cough, hemoptysis, left flank pain and gross hematuria. Initial presentation …

Role Of Artificial Intelligence In Endoscopic Intervention: A Clinical Review, Nismat Javed, Haider Ghazanfar, Bhavna Balar, Harish Patel

Journal of Community Hospital Internal Medicine Perspectives

Gastrointestinal diseases are increasing in global prevalence. As a result, the contribution to both mortality and healthcare costs is increasing. While interventions utilizing scoping techniques or ultrasound are crucial to both the timely diagnosis and management of illness, a few limitations are associated with these techniques. Artificial intelligence, using computerized diagnoses, deep learning systems, or neural networks, is increasingly being employed in multiple aspects of medicine to improve the characteristics and outcomes of these tools. Therefore, this review aims to discuss applications of artificial intelligence in endoscopy, colonoscopy, and endoscopic ultrasound.

Nsaids Role In Triggering Ibd Exacerbations; Reality Or Misunderstanding? A Systematic Review, Alec Swartz, Malitha Hettiarachchi

Conference Presentation Abstracts

Introduction: Initial studies seemed to show that NSAID use was associated with increased risk of IBD exacerbation. Supported by known role of COX-1/2 isoenzymes (specifically their prostaglandin [PG] products) in maintaining GI mucosal barrier and mediating inflammation Combination of early research findings and COX prostaglandin knowledge resulted in NSAID avoidance in IBD patients. Recent data seemingly contradicts prior research, and NSAID use is predicted to not play a role in IBD exacerbation Methods: We conducted a systematic review of the literature using PubMed and American Journal of Gastroenterology. Of the thousands of results, we narrowed our results to 4 recent …

Conference Presentation Abstracts

Patients with Waldenstrom's macroglobulinemia/lymphoplasmacytic lymphoma are at increased risk of sinopulmonary infections, pyelonephritis, and septicemia. The underlying etiology is assumed to be immune dysregulation. Patient's with Waldenstrom's macroglobulinemia have been shown to have somatic mutations in the "V". "D" and "J/H' segments of immunoglobulin gene. These mutations can affect affinity maturation and formation of memory B cells. Subsequently patient's with Waldenstrom's macroglobulinemia also have a suboptimal response to vaccination against Staphylococcus aureus, Streptococcus pneumoniae and Varicella, similar to those with multiple myeloma. Severe infections with gram positive organisms causing multifocal osteomyelitis, pleural effusion and sepsis have also been reported with …

Double Trouble Unmasked: Femoral Pseudoaneurysm And Deep Venous Thromboses Following Coronary Angiography, Mariam Jamil, Antoine Egbe, Khurram Arshad, Yazan Alamro, Essa Kadiri

Conference Presentation Abstracts

Iatrogenic pseudoaneurysms, while infrequent, represent a formidable complication of interventional cardiac catheterization, particularly in cases involving femoral artery access. This report details a unique case involving a 73-year-old male, receiving warfarin for a mechanical aortic valve, who developed a substantial right groin hematoma attributed to an iatrogenic pseudoaneurysm post-cardiac catheterization, subsequently resulting in concomitant deep venous thromboses (DVTs) in the right leg. The pathophysiology of DVTs following left heart catheterization typically involves the formation of a sizable pseudoaneurysm, exerting pressure on adjacent veins, leading to blood pooling and subsequent clot formation. Alternatively, the development of large hematomas in the thigh …

Effect Of Iv Iron-Carbohydrate Supplement On Morbidity And Mortality In Patients With Heart Failure, Yousef Alsmairat, Malitha Hettiarachchi

Conference Presentation Abstracts

Objectives: To study the effect of intravenous iron on morbidity and mortality in hospitalized patients with heart failure with reduced ejection fraction. The current European Society of Cardiology's 2021 heart failure guidelines recommend the consideration of Ferric Carboxymaltose in symptomatic patients with a left ventricular ejection fraction < 45%. Methods and results: We conducted a systematic review using articles published in PubMed and EMBASE databases. The number of records first identified was 263. The study only reviewed Randomized Clinical Trails (RCTs) published in the years 2013-2023 and removed all the duplicates and irrelevant articles using Rayyan.ai tool. The final number of qualified articles that met the study's inclusion criteria was 3, with a total of 2,279 participants. The inclusion criteria for the study included: Age > 18, and heart failure (HF) with left ventricular ejection fraction (LVEF) < 50%. The study showed that intravenous iron supplementation in patients with heart failure and iron deficiency has been proven to reduce the symptoms of heart failure, improve quality of life, increase exercise capacity and skeletal muscle strength. IV iron-carbohydrate therapy significantly reduced hospitalization for worsening heart failure, but did not significantly impact all-cause mortality, compared to control. Conclusion: IV iron-carbohydrate therapy significantly reduced hospitalization for worsening heart failure, but did not significantly impact all-cause mortality, compared to control. Based on the study review, we recommend IV iron therapy for patients with systolic dysfunction heart failure associated with iron deficiency anemia.

Aggressive Renal Cell Carcinoma In A Patient With A Rare Genetic Syndrome, Nidhi Navaratna, Nitya Batra, Mohammad Chisti

Conference Presentation Abstracts

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is an exceedingly rare genetic disorder characterized by skin and uterine leiomyomas and an increased risk of renal cell cancer. HLRCC follows an autosomal dominant pattern and is due to inactivating germline and somatic mutations in the gene encoding the fumarate hydratase enzyme (FH) involved in the citric acid cycle. The rarity and wide phenotypic variation in the presentation of HLRCC complicates suspicion and testing for this syndrome. We describe the case of a young woman who presented with pathological fracture secondary to bone metastasis from renal cell carcinoma. The patient presented to …
